A clinical dilemma: cardiac and pericardiac echinococcosis.

BACKGROUND: Cardiac and pericardial echinococcosis as a life-threatening disease may present with a clear picture most of the time, however it may also become a clinical puzzle. METHODS: In the period between 1977 and 1998, 14 patients were operated on with the diagnosis of cardiac and pericardial echinococcosis. Nine patients were operated on with standard cardiopulmonary bypass (CPB) techniques, and the remaining 5 patients were operated on without CPB. Transesophageal echocardiography (TEE) or intraoperative surface echocardiography were used to plan and perform the operation for the late cases. RESULTS: One patient died during the postoperative period due to the rupture of interventricular septum. All other patients survived the perioperative period, received mebendazole treatment, and exhibited no recurrence during the follow-up. CONCLUSIONS: The definitive treatment is the surgical extraction of the cyst. Because the clinical picture may vary according to the number, size, and location of cysts, as well as complications, cardiac echinococcosis should be remembered and included in the differential diagnosis to achieve the treatment. Intraoperative surface echocardiography is of paramount value for diagnosis and planning the management of a successful surgery.

Carotid disease in patients scheduled for coronary artery bypass: analysis of 678 patients.

The purpose of this article is to investigate the frequency of carotid disease and to identify high-risk groups among patients scheduled for isolated coronary artery bypass grafting (CABG) procedures under nonemergent conditions. A total of 678 consecutive patients underwent preoperative carotid artery duplex scanning (CADS) before CABG procedures. Morphology of carotid artery was determined and five groups were formed. Age, sex, cervical bruit, diabetes mellitus (DM), hypertension, smoking, history of cerebrovascular event (CVE), peripheral vascular disease (PVD), and severity of coronary artery disease were investigated to describe the high-risk group for carotid artery disease. In 41% of patients carotid examination produced normal findings; 46.2% had less than 60% luminal stenoses, 7.1% had 60-79% stenoses, 4.6% had 80-99% stenoses, and 1.2% had total occlusion. Previous cerebral ischemic events (CVE) (p<0.05), hypertension (p < 0.01), smoking (p < 0.01), advanced age (p < 0.01), and female sex (p < 0.01) were identified as high-risk factors for carotid artery stenoses. There was a linear association between carotid disease and coronary disease (p < 0.05). Documentation of previous CVE, hypertension, smoking, advanced age, female sex, and severe coronary artery disease may be helpful in identifying patients at high risk for carotid artery stenoses.

Hepatic vein Doppler waveform changes in early stage (Child-Pugh A) chronic parenchymal liver disease.

Doppler waveform changes can be found in chronic parenchymal liver disease, especially in the late stages. We investigated the contribution of Doppler ultrasound in diagnosing early-stage chronic parenchymal liver disease. In this prospective study, 30 patients who had been diagnosed with chronic liver disease (Child-Pugh class A) and 30 healthy subjects were studied. The diagnosis was confirmed with histopathologic examinations of biopsy specimens in 17 patients. The Doppler US examination of hepatic veins was performed in all the patients and healthy subjects. The Doppler US pattern was classified into three groups according to the Doppler signal characteristics: (1) type 0, triphasic waveform, the presence of a short phase of reversed flow, (2) type I, decreased amplitude of the phasic oscillations without the short phase of reversed flow, and (3) type II, complete flat waveform. Normal hepatic vein waveforms (type 0) were found in 8 patients (26.66%) and abnormal hepatic waveforms (type I + type II) in 22 patients (73.33%). The results of Doppler ultrasonography were correlated with the diagnosis of early-stage chronic parenchymal liver disease (Child-Pugh class A). In all the subjects of the control group, the Doppler waveform of hepatic veins showed the triphasic pattern (type 0). In the statistical evaluation using Fisher's exact test we observed that there was a significant difference (p < 0.05) between the control group and the patient group with respect to the presence of abnormal (type I + type II) Doppler waveform. The diagnostic accuracy in the patients who had biopsy was 76.47% and that in the patients who did not was 69.23%.

Primary malignant lymphoma of the bladder. A case report and review of the literature.

Primary malignant lymphoma of the bladder is unusual. We report a case of primary malignant lymphoma arising in the urinary bladder. A 54-year-old woman was admitted to our hospital with the chief complaint of dysuria, on May 26, 1995. Examination of IVP, ultrasonography, cystoscopy suggested a non-papillary bladder tumour. Diagnosis was established by histological examination.

Reconstruction of ureteral defects with a tubular skin graft secondarily prefabricated utilizing omentum as a carrier: an experimental study.

OBJECTIVES: This study was conducted to evaluate reconstruction of the ureter in dogs after resection of a 7-cm-long midlength segment with a vascularized tubular skin graft secondarily prefabricated utilizing omentum as a carrier. METHODS: Nine female mongrel dogs underwent surgery in which omental surface capabilities were used to create a vascularized prefabricated skin graft. After 4 weeks, all 9 dogs underwent the second surgical procedure, which included the resection of a 7-cm-long segment from the ureter and an interureteral anastomosis of the omentocutaneous cylindrical tube. At postoperative week 10, just before the third surgical procedure, intravenous urography was performed to evaluate the continuity of the treated ureter. Nephroureterectomy was also performed immediately after intravenous urography to obtain specimens for histologic analysis of the aforementioned tubular anastomosis. RESULTS: The continuity of the ureteral defect was restored with the help of the omentocutaneous cylindrical tube. There was no narrowing throughout the ureter and along the omentocutaneous cylindrical tube. Only minimal dilation occurred at the neoskin tube and at the ipsilateral collecting system. Histopathologically, there were capillary protrusions entering the skin graft from the omental vasculature. The columnar epithelium of the cutaneous cylindrical tube was completely preserved, and transitional ingrowth was present at the proximal and distal ends of the tube. CONCLUSIONS: The surgical procedure resulted in successful reconstruction of ureteral continuity by the use of a prefabricated omentocutaneous cylindrical tube in dogs.

Mesenteric panniculitis.

Mesenteric panniculitis is a non-neoplastic inflammatory process affecting the adipose tissue of the mesentery. It is an extremely rare disease. We report the case of a 30-year-old man with mesenteric panniculitis and describe the radiologic findings.

Sonourethrography in anterior urethral stricture: comparison to radiographic urethrography.

Twenty-three male patients with known or suspected urethral stricture disease were evaluated using sonourethrography and standard retrograde x-ray urethrography for comparative analysis of two techniques. Results were evaluated statistically. These two methods can substitute each other in determining the stricture area length of anterior urethra. Due to advantages, if both of these methods are used combining each other, we believe that they will be much more sensitive.

Duodenal phytobezoar: a case report and review of the literature.

Phytobezoars are an unusual cause of small bowel obstruction. We report a case of small bowel obstruction due to phytobezoar in a 63 year-old female patient who had undergone gastric surgery (truncal vagotomy with pyloroplasty) for duodenal ulcer disease complicated by gastric outlet obstruction 10 years ago. We diagnosed this bezoar case by radiologic methods and these methods keep their importance for the diagnosis of small bowel obstruction with phytobezoars.
